Features

Reliable Operation
1. All parts and control components of the unit are provided by world-famous reliable suppliers to make the unit highly efficient, energy saving, and reliable, such as Bitzer Comp. & Danfoss EXV, Schneider electric etc.
2. The unit uses the advanced electronic expansion valve, which ensures excellent performance both under full load or partial load and higher control accuracy (Optional)
3. Each unit was extensively tested before delivery to verify its operational reliability and to ensure a smooth startup.

Easy and Fast Installation
1. The water pipe of the water-side heat exchanger has been equipped with water flow switch and is ready to use, which saves the job site installation time. Inlet and outlet pipes are equipped with flange connection, which makes the on-site installation easier.
2. The Chiller comes with the startup cabinet and control cabinet and has been filled with refrigerant and refrigeration oil before delivery. The chiller can be placed in service after being connected with power supply and water supply during field installation.
3. The built-in hydronic module is optional. This module integrates all necessary hydronic components such as water pump, filter, expansion tank, flow switch, safety valve, pressure gauge, and drainage valve.

Components
1. High efficiency Bitzer screw compressor, Hanbell screw compressor is optional.
2. High efficiency heat exchanger. 
Condenser adopts the copper tube & hydrophilic aluminium fin coil type structure, the appearance is V-shape. This design increase the heat exchange area, reduce the temp. differences, thus increase the heat exchange efficiency by 20%. Evaporator built with high efficiency shell & tube type heat exchanger, factory insulated with flexible close cell material.
3. 
External rotor type axial fans, equipped with three phase direct drive motors, low noise 8 poles, protection level IP54, provided with a protective outlet grille.
4. 
Electric panel consist of: compressor contactor, fan motor contactor, compressor isolating switch, fan protection breaker, phase sequence relay and microprocessor with function display. All of them are Schneider Electric brand.
